RMTT Sensor Sample

[ggasteratos]

Hi, I wrote a simple program that turns a LED on when a sensor detects smoke. I have a LED and a smoke sensor MQ-2 connected to RMTT. I upload the code from Arduino IDE to the Expansion module RMTT via USB and it works fine.

void setup() {
pinMode(21, OUTPUT); //led pin
pinMode(4, INPUT); //sensor pin
}

void loop() {
if(analogRead(4)> 500){
digitalWrite(21, HIGH);
//SET THE ALARM HERE...
}else
digitalWrite(21, LOW);
delay(100); // delay between reads
}

What I need is, to be able to sound an alarm on the mobile app which controls the drone. Is it possible?

Thanks in advance,
Greg.

Because I see there is very little information about uploading code to the RMTT via the Arduino IDE I have create some instruction here. Sending code the RMTT expansion module?
